We divide 587309 by 80
We want to divide 587309 by 80.

Let's proceed to step 1:
If we divide 5 by 80, we get 0 and a remainder of 5.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 5, we get 5.
Take the next digit (8) from the dividend and append it to 5, then repeat: 58 / 80

Moving on to step 2:
If we divide 58 by 80, we get 0 and a remainder of 58.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 58 leaves us with 58.
Fetch the next digit (7) from the dividend, attach it to 58 and continue: 587 / 80

Going ahead to step 3:
If we divide 587 by 80, we get 7 and a remainder of 27.
Record the quotient 7 as the next digit in the result. 
Result so far: 7.0
Deduct 560 from 587 and we're left with 27.
Fetch the next digit (3) from the dividend, attach it to 27 and continue: 273 / 80

Let's proceed to step 4:
The number 80 fits into 273 3 times, leaving a remainder of 33.
The number 3 becomes the next digit in our result. 
Result so far: 73.0
If we subtract 240 from 273, we get 33.
Take the next digit (0) from the dividend and append it to 33, then repeat: 330 / 80

Step 5:
330 divided by 80 is 4 with a remainder of 10.
The number 4 becomes the next digit in our result. 
Result so far: 734.0
Deduct 320 from 330 and we're left with 10.
Bring next digit (9) of the dividend behind the 10 and repeat the process: 109 / 80

Step 6:
When dividing 109 by 80, we get 1 with a remainder of 29.
The number 1 becomes the next digit in our result. 
Result so far: 7341.0
Subtracting 80 from 109 leaves us with 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

Going ahead to step 7:
80 goes into 290 3 times with a remainder of 50.
The number 3 becomes the next digit in our result. 
Result so far: 7341.3
Subtract 240 from 290 to get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Step 8:
80 goes into 500 6 times with a remainder of 20.
Put 6 as the next digit of the answer. 
Result so far: 7341.36
Deduct 480 from 500 and we're left with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Going ahead to step 9:
When dividing 200 by 80, we get 2 with a remainder of 40.
The number 2 becomes the next digit in our result. 
Result so far: 7341.362
Deduct 160 from 200 and we're left with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Step 10:
If we divide 400 by 80, we get 5 and a remainder of 0.
Use 5 as the next digit of our solution. 
Result so far: 7341.3625
If we take 400 away from 400, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Let's proceed to step 11:
80 can be fit into 0 0 times, resulting in a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 7341.3625
If we take 0 away from 0, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Moving on to step 12:
If we divide 0 by 80, we get 0 and a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 7341.3625
If we take 0 away from 0, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

After the division, we end up with 7341.3625 and a remainder of 0.0.
